ENGR 120: Programming for Engineers Homework Assignment \# 3 Spring 2023 Due Thursday Feb 9 at 11 am Note: This is not a programming assignment, however, feel free to use CLion to answer the questions. Problem 1 Write this equation as a C statement using functions exp,log, and pow : y=enln(b) Problem 2 Rewrite the following mathematical expressions using C functions such as abs and pow: f=xyzw Problem 3 Write statements that compute and display the absolute difference of two type double variables, x and y that is xy. Problem 4 A C expression is given by y=pow(exp(nlog(b)),2); Write the corresponding mathematical expression. Problem5 Write a C function to implement the following math function. f=xyzw where x,y,w are of type double and z is an integer. The function should return a double. Show how to call the function when x=12.25,y=23.35,w=25.25,z=5
